vapor pressure of solutions

Let us suppose a small amount of a non-volatile solute (sugar) is dissolved in a solvent (water). When evaporation of this solution takes place, only water evaporates as the other component (i.e., sugar) is non-volatile. The vapor pressure of the s..

The relative lowering of vapor pressure is a colligative property as it depends only on the concentration of the solute and it is independent of its nature. Consider a binary solution consisting of non volatile solute in a volatile solvent. The ..

In 1886 the French chemist Francois Marie Raoult carried out a series of experiments to study the vapor pressure of a number of binary solutions containing non-volatile as well as volatile non electrolyte solutes. On the basis of the results of the experiment..

Vapour pressure is defined as the partial pressure exerted by the vapors above the liquid surface in equilibrium with liquid at a given temperatur..

Vapour Pressure of Liquids - Vapour pressure is defined as the partial pressure exerted by the vapors above the liquid surface in equilibrium with liquid at a given temperature. fig 3.3 In illustrations 1a and 1b, the liquid and vapor states of a gi..

Osmotic pressure is the pressure required to prevent the net movement of pure water into a solution so as to prevent the volume of the solution from increasi..

The pressure built up inside the cells as a result of the entry of water is called osmotic pressure. The entry of water into the cells is regulated by the solutes in the cell. Less concentration of solutes means more concentration of water. Positive osmotic h..

The excess pressure that must be applied to the solution/conc.solution to prevent osmosi..

For a given solvent the osmotic pressure depends only upon the molar concentration of solute but does not depend on its nature. The following relation relates osmotic pressure to number of moles of solute: p V=nRT Van't Hoff 's solution equation ( p..
